Hi folks,
I have acquired 561A which looks in decent condition visually but the HV transformer and associated valves and caps are all missing. I can see somebody attempted to make replacement HV supply and failed in doing so and put the scope to side. When his kids were doing a cleanup I bought it without checking as it was cheap enough and I don't have any valve Tek scope.
Rest of the HV supply is easy to make using diodes and fresh new caps but the transformer is a show stopper. I couldn't find many floating about for sale but by an off chance aren't the original transformer specs available? I can have one made but it will be much easier if I know the exact spec.
